A drive head for a windscreen wiper assembly is pressed from sheet steel to define two side walls 1 and 2 and adjoining top wall 3. At one end holes 4 are provided in the side walls 1 and 2 to receive a pivot pin for a wiper arm retainer. At the other end the sheet metal is deformed to create a conical projection 5 which has a DIN taper equivalent to that of the head of a drive shaft from the windscreen wiper motor. When the tapered head of the drive shaft is located into the projection 5, a nut 9 is screwed onto a threaded end of the drive shaft to drive a washer 10 into engagement with the projection 5 so as to lock the drive shaft 6 securely to the drive head. The projections 5 could, in alternative design, project up within a recess formed in the other end of the drive head 1. <IMAGE> |
